Working normally, if a Kidde detector goes off on one level, then it communicates with detectors on all levels and they go off too. The defective one kept signaling the other alarms to go off. I pulled the hard-wire and ran it on battery, but knew something was wrong and thought it was something in the house. Then Amazon gave me a refund. Installed a new Kidde and it works fine.

Automatically? Who are you really, rab can but wonder. Thanks for the come back anyhow.
